Quite short wavelength light in sunlight (UVC and short wavelength UVB) is poisonous to animal eyes and skin, along with the air blocks it. Natural sun extends from approximately 290 to 295 nanometers, which can be from the UVB range, to over 5,000 nanometers, which can be from the long-wavelength infrared (heat) range.
Infrared light is sunlight's heat, also
Reptile Basking Spot Lamps absorb infrared radiation exceptionally effectively through their own skin. This component of the
full spectrum daylight bulb is imperceptible to humans and many reptiles, but a few snakes can comprehend the more wavelengths (over 5,000 nanometers) throughout their facial pit organs. Ceramic heaters and heating mats emit just infrared. Incandescent lamps emit visible and infrared light. Some incandescent red basking lamps are called "infra-red" lamps, but these additionally exude red visible light.
